Being trans and the whole transitioning process will still exist with or without puberty blockers. But the decisions to make the bodily and chemical alterations that some people desire (to round-off square jaws, surgically remove breasts, shape penis-like appendages, hollow out the pelvic area to construct vagina-like orifices etc... ) will be decisions taken by ADULTS, who fully understand the implications of drug contraindications, risks of anaesthesia, the enormity of major elective surgery etc...
People like Paris Lees and Munroe Bergdorf have gone through some of these procedures and are a completely happy with the results it would seem. They look amazing and that’s obviously very important to them. Facial feminisation can totally change your look. (I could do with it myself!)
Give gender dysphoric children good therapy and emotional support. Let them dress how they want and change their names. Tell them that if they want to adjust their bodies in the future then they can.
I would explain to any child that the Court decision today is just like pressing a ‘pause button’ on a medical process that is irreversible and that they may have gone on to regret. We are trying to protect them and it comes from a place of love, not from a place of transphobia.
